To Han Yeong, he has the image of someone who does 'only' what he's told and surprisingly needs a lot of looking after.

He has a puppy-like eye shape with downturned corners, deep green hair with a 7:3 part, and matching eyes. He has a dimple on one cheek, but it's rarely seen since he doesn't smile often.
